Daily diet soda may increase risk of heart attack, stroke

Gardener and her team studied 2,564 New York City adults who were 69 years or older at the study's start. Over the next decade, 591 men and women had a heart attack, stroke or died of cardiovascular causes -- including 31 percent of the 163 people who drank a diet soda daily at the start of the study.
Overall, daily consumption of diet soda was linked to a 44-percent higher chance of heart attack or stroke, compared with 22 percent for people who rarely or never drank diet soda but had a heart attack or stroke.
Gardener said that if diet soda itself contributes to health risks, it's not clear how.
Some research in rats suggests that artificial sweeteners can end up boosting food intake and weight, but whether these results translate to humans is unknown.

Treating Depression: Is there a placebo effect?



Here is a 13 minute video of an interesting 60 Minutes story that looks at how the placebo effect can be used to treat depression. This connects to the power of the mind and how simply by thinking we are taking a pill that will make us feel better people can feel better.

A Harvard scientist says the drugs used to treat depression are effective, but for many, it's not the active ingredient that's making people feel better. It's the placebo effect.

Growing Support for Drug Testing of Welfare Recipients



Conservatives who say welfare recipients should have to pass a drug test to receive government assistance have momentum on their side.
The issue has come up in the Republican presidential campaign, with Mitt Romney calling it an “excellent idea.”
Nearly two dozen states are considering measures that would make drug testing mandatory for welfare recipients, according to the National Conference of State Legislatures. Wyoming lawmakers advanced such a proposal last week.
Driving the measures is a perception that people on public assistance are misusing the money and that cutting off their benefits would save money for tight state budgets — even as statistics have largely proved both notions untrue.

Qnexa FDA Approval: Facts on and Side Effects of the Newest Weight-Loss Drug

Qnexa, a new weight loss drug produced by Vivus, received a nod of favored approval from the U.S. Food and Drug Administration Advisory Committee on Wednesday. An official approval or a rejection will be announced on April 17. 
In a vote of 20 to 2 for approval, the FDA committee stated that Qnexa's weight loss benefits for the chronically obsess outweighed the risks the drug may pose, reported ABC News.

Qnexa is a combination of two drugs - phentermine, which is a stimulant, and topiramate, an epilepsy and migraine drug also known by the name Topamax.
According to The Times, use of Qnexa led to an average weight loss of approximately 10 percent body weight after one year. However, some of that lost weight was gained back in the second year of use.
Qnexa also reportedly demonstrated positive effects on blood pressure and blood sugar, lowering both. It also helped improve the individual's quality of life.

Tipsy Fruit Flies On A Mission

Tipsy Fruit Flies on a Mission

Fruit flies may seem as if they lead an uneventful life. They look for old fruit to lay their eggs. The maggots then hatch and graze on the yeast and bacteria that make the fruit rot.

In reality, however, these flies have to do battle with horrifying enemies. Tiny wasps seek out the maggots and lay eggs inside them. The wasps develop inside the still living flies, feeding on their tissues. When the wasps reach adult size, they crawl out of the dying bodies of their hosts.

The flies are not helpless victims, however. In the journal Current Biology, Todd Schlenke, an Emory University biologist, and his colleagues report a remarkable defense the insects use: To kill their parasites, the flies get drunk.

Dr. Schlenke discovered this tactic while studying the common fruit fly species Drosophila melanogaster. As they eat yeast, they also eat the alcohol that the yeast produce while breaking down sugar. Their fermentation can leave a rotting banana with an alcohol concentration higher than that of a bottle of beer.

This boozy environment can be toxic to animals. The only reason Drosophila melanogaster thrives on rotting fruit is that it has evolved special enzymes that quickly detoxify alcohol.

Dr. Schlenke was well aware that many insects gain defenses from their food. Monarch butterflies, for example, are protected from birds by the toxic compounds they get from the milkweed plants they eat. To see how alcohol influences the enemies of the flies, Dr. Schlenke unleashed a parasitic wasp, Leptopilina heterotoma.

Dr. Schlenke allowed the wasps to attack two kinds of fly larvae: one kind reared on alcohol-free food, and another that ate food spiked with 6 percent alcohol. In the presence of alcohol, the wasps laid 60 percent fewer eggs, possibly because of the fumes wafting from the food. “Presumably the wasps felt really ill,” Dr. Schlenke said.

It turned out that alcohol was even worse for their eggs. Wasps growing in flies that ate alcohol-free food always grew normally. But inside boozing flies, 65 percent of the wasps died.

Dr. Schlenke discovered they suffered a hideous death: Each wasp’s internal organs had shot out of its anus. “All their guts are outside the wasps,” he said. “I don’t know how to explain that.”

This deadly effect occurred only if the flies consumed alcohol after the wasps laid eggs in them. Taking in alcohol beforehand, by contrast, had little effect. This discovery led Dr. Schlenke to wonder if the flies might seek out alcohol to kill the wasps, using it like a medical drug. “I wondered if they were smart enough to know that,” he said.

To find out, he and his colleagues filled petri dishes with alcohol-rich food on one side and alcohol-free food on the other. They then placed flies that did not have wasps inside them on the alcohol-free side. A day later, they found that 30 percent of the flies had crawled over to the side with alcohol. When they repeated the experiment with wasp-infested flies, 80 percent of the flies headed for the spirits. “There’s a big difference there,” Dr. Schlenke said.

Likewise, when the flies started out on the alcohol side of the dish, 40 percent of the healthy flies crawled to the other side after 24 hours. Many infected larvae started moving to the other side as well, but then returned to the alcohol. Dr. Schlenke speculates that they were exploring for even higher alcohol concentrations that would be even more toxic to their parasites.

“They know the wasps are infecting them, and they seek out the alcohol,” Dr. Schlenke said. “The flies self-medicate by getting schnockered.”

Some wasps appear to have evolved ways around this tipsy defense. Dr. Schlenke repeated these experiments on another species, L. boulardi, which unlike the other wasp can lay its eggs only in D. melanogaster. Dr. Schlenke found that the specialist wasp L. boulardi suffered far less when its host consumed alcohol. Only 10 percent of its larvae died, compared with 65 percent for L. heterotoma. Dr. Schlenke suspects that its specialization allowed L. boulardi to overcome the alcohol. “The wasps are tracking their hosts over evolutionary time,” he said.

“This article is exciting in several ways,” said Michael Singer, a biologist at Wesleyan University who was not involved in the study. Over the years, scientists have gathered a few examples of animals medicating themselves. Chimpanzees eat plants with antiparasitic compounds when they get intestinal worms, for example. Dr. Singer and his colleagues have shown that woolly bear caterpillars go out of their way to feed on toxic plant leaves when parasitic flies lay eggs in them. But Dr. Schlenke’s research is the first to show that an animal uses alcohol as medicine.

Alcohol is common in nature, and Dr. Schlenke speculates that other species may seek it out to self-medicate. When it comes to humans, however, Dr. Schlenke has no idea whether a bout of heavy drinking has any effect on a parasite.

“As far as I can tell, no one’s ever tested whether we humans can make life hard for our bloodborne pathogens by getting our blood alcohol levels up,” he said.

Drinking and Drugging

By FRANK BRUNI 

“CRACK is wack.”
Remember that phrase? I heard many people repeat it last week as they appraised the waste of Whitney Houston’s later years and flashed back to her 2002 interview with Diane Sawyer, when she uttered those immortal words. She was bristling not at rumors that she abused drugs but at insinuations that she turned to cheap ones. With album sales like hers, you didn’t have to suck on a pipe. 

Sawyer wanted to know what Houston was on. Everyone wanted to know what Houston was on, and news reports after her death took unconfirmed inventory of the pills in her hotel suite, wondering if they represented the extent of her indulgences.

Cancer Drug Counterfeiting

Fake Cancer Drug Found in U.S.

The maker of the widely used Avastin cancer drug said Tuesday that it is warning doctors, hospitals and patient groups that a counterfeit version of the medicine has been found in the U.S.
Swiss drug maker Roche said it is warning doctors, hospitals and patient groups that a counterfeit version of its widely used Avastin cancer therapy was found in the U.S. Jonathan Rockoff has details on The News Hub. Photo: AP
Tests of counterfeit vials of Avastin showed that they didn't contain the active ingredient in Roche Holding AG's intravenous drug, according to the Swiss company's Genentech unit.
It isn't clear how much of the counterfeit product was distributed in the U.S. or whether it has caused any harm. A Genentech spokeswoman said the company doesn't know if any patients were given the fake drug.
The Food and Drug Administration is investigating, and has sent letters to 19 medical practices in the U.S. that the agency says buy unapproved cancer medicines and might have bought the counterfeit Avastin.
An FDA spokeswoman said it hasn't received any reports of patient side effects that appear to be linked to the counterfeit product.
Most Americans don't question the integrity of the drugs they rely on. They view drug counterfeiting, if they are aware of it at all, as a problem for developing countries. But the latest incident, which follows the appearance of other fake drugs in the U.S.—including counterfeits of the weight-loss treatment Alli and the influenza treatment Tamiflu—suggests it is a growing risk, especially as more medicines and drug ingredients sold in the U.S. are made overseas.
In addition to the specter of fake medicines, U.S. drug makers are confronting their own shortcomings. Companies including Johnson & Johnson have had to shut down manufacturing plants due to quality problems. Earlier this month, Pfizer Inc. said it recalled about a million packs of birth-control pills because improper packaging could raise the risk of unplanned pregnancies.
Roche still is testing the vials of counterfeit Avastin to see what ingredients they contain, but the Genentech spokeswoman said: "It's not Avastin. It's not safe and effective, and it shouldn't be used."

The maker of the widely used Avastin cancer drug said that it is warning doctors, hospitals and patient groups that a counterfeit version of the medicine has been found in the U.S.
Genentech said it is asking health-care providers to report any suspected counterfeits to the FDA's Office of Criminal Investigations.
Avastin belongs to a class of cancer therapies that interferes with the development of new blood vessels that tumors need to grow. The pricey drug, often used with chemotherapy, is for certain patients with colon, lung and other cancers. The drug was at the center of a controversy last year, because the FDA withdrew approval for its use for breast cancer, angering many patients.
A 400-milligram vial of Avastin—the size that was counterfeited—costs $2,400, according to the Genentech spokeswoman.
Last year, Genentech's sales of Avastin in the U.S. generated more than $2.5 billion, the spokeswoman said. Many patients receive it intravenously, typically in a hospital or doctor's office, every two or three weeks for as long as a year.
"Most [cancer] doctors in an average workweek will be using it. It is a commonly used drug," said Leonard Saltz, who runs the colorectal oncology section at Memorial Sloan-Kettering Cancer Center in New York.
Dr. Saltz, who also chairs the pharmacy committee monitoring the safety of Sloan-Kettering's drug supply, said the Avastin news will prompt doctors and hospitals to double-check their sourcing of the product and make sure their supplies are safe.
Experts say counterfeits are a relatively small but still serious problem for the nation's drug supply. In the U.S., most prescription medicines are distributed by authorized suppliers, who buy them from their manufacturers and assure their integrity. Pharmacies, too, put pressure on the distributors to ensure quality.
Still counterfeits can enter the drug supply through unauthorized distributors and Internet pharmacies that try to turn a quick profit selling the inauthentic products. Doctors and patients might not know they are using a counterfeit if it doesn't cause harm but simply fails to work.
The counterfeit Avastin was packaged in boxes and vials whose markings were clearly different from the authentic product, according to the Genentech spokeswoman. In the U.S., boxes of authentic Avastin are labeled in English, say they were made by Genentech and have a six-digit lot number with no letters. The counterfeit boxes had writing in French, identified Roche as the manufacturer, and had lot numbers on the boxes or vials starting with B86017, B6011 or B6010.
Roche first learned there might be a counterfeit problem when an unnamed foreign health authority notified the company in December of inauthentic Avastin made overseas and said it was investigating, the Genentech spokeswoman said. Later, the FDA warned the company. The FDA said it was alerted by the Medicines and Healthcare Products Regulatory Agency in the U.K.
On Friday, the FDA sent letters to 19 medical practices, mostly in California, that the agency said had bought medicines from the suppliers of the counterfeit Avastin. The two-page letters identified the suppliers as Quality Specialty Products, which the FDA said also might be known as Montana Health Care Solutions. The letter said that QSP's products are distributed by Volunteer Distribution in Gainesboro, Tenn.
"A high percentage of these products are injectable cancer medications whose quality could be adversely affected if they are not stored or transported under specific temperatures," the letter added.
QSP and Volunteer Distribution couldn't be reached for comment Tuesday night, nor could 17 of the 19 medical practices.
"I did not have the Avastin they were referring to," said Naresh Gupta, a Plano, Texas, oncologist who received the FDA's letter Monday. He said he purchased Avastin for his practice from a large national drug distributor that wasn't named in the FDA's announcement.
A second doctor, Raymond Heung, of San Diego, said he didn't know anything about the Avastin problems or the FDA letter.
In its letter, the FDA asked the medical practices to "cease using and retain and secure all remaining products" from the suppliers. It also issued a general warning to medical practices asking them to "stop using" any products they might have from the two companies and report any suspect items that the companies supplied.
The Genentech spokeswoman said none of the suppliers identified by the FDA are authorized to distribute Avastin. "Genentech limits the distribution of many of its products and only sells its products directly to a defined number of fully licensed and contracted wholesalers and specialty distributors," she said.
Counterfeiting has historically been more of a problem outside the U.S. Counterfeit Avastin was injected into the eyes of 116 patients at a Shanghai hospital, resulting in an outbreak of complications, hospital officials reported last year in a letter to the New England Journal of Medicine. The active ingredient in Avastin is sometimes used to treat macular degeneration, a disease that causes vision loss, though it isn't approved for that use in the U.S.
Concerns about counterfeit drugs sold in the U.S. have grown as more products and their ingredients are made abroad. The FDA has been issuing warnings about counterfeits on average once or twice a year.
In 2010, fake versions of the over-the-counter weight-loss drug Alli were being sold over the Internet. The counterfeit versions didn't contain the active ingredient in Alli and instead contained sibutramine, the active ingredient in the prescription-strength weight-loss drug Meridia, which has since been removed from the U.S. market because of concerns the drug increased the risk of heart attacks.
Also in 2010, the FDA warned consumers that a product sold as "Generic Tamiflu," an influenza treatment, was actually a counterfeit containing a penicillin-like antibiotic, rather than flu-fighting antiviral drugs. And a Belgian man pleaded guilty in a U.S. court last year to selling $1.4 million worth of fake or misbranded drugs, including potentially phony Viagra and Lipitor, both Pfizer drugs, over the Internet.
U.S. customs agents and regulators are spot-checking drug imports with increasingly sophisticated laboratory equipment, but the growing volume of shipments has made it "increasingly difficult for us to regulate our own supply chain," said Tom Woods, of Woods International LLC, a consulting firm that advises on avoiding drug counterfeiting.

Primed for Addiction?

This article from Science questions the validity of claims about how drug addiction can adversely affect brain function. Researchers were interested to find if brain function that limits decision making and self-control was a product or a cause of drug use/addiction. The experiment compared brain scans of two siblings, one a drug user/addict and one not. The results show that addicts and siblings of addicts tend to show very similar scans. This suggests that there must be some other prevailing force (besides genetic factors) that inclines easily addicted personalities to use drugs. 

 This article might be a great primer for our lecture on Thursday.

Whitney Houston's bodyguard 'found her drowned in bath in her hotel room'

Miss Houston drowned alone in a bathtub having accidentally overdosed on a cocktail of prescription drugs and alcohol after two back-to-back evenings of out-of-control binges, it has been claimed.

The star was found dead under the water by her bodyguard in a luxury hotel suite said to have been littered with bottles of prescription pills. She was 48. 

Bottles of Lorazepam, Valium, Xanax and a sleeping medication were found in the hotel room, it has been claimed. The drugs were believed to have acted as sedatives, causing her to fall asleep in the bathtub once they had been mixed with alcohol from the previous evenings.

Shippensburg University Dispenses 'Morning-After' Pill From A Vending Machine




Students at Shippensburg University in Pennsylvania can get the "morning-after" pill by sliding $25 into a vending machine, an idea that has drawn the attention of federal regulators and raised questions about how accessible emergency contraception should be.
The student health center at Shippensburg, a secluded public institution of 8,300 students tucked between mountain ridges in the Cumberland Valley, provides the Plan B One Step emergency contraceptive in the vending machine along with condoms, decongestants and pregnancy tests.
"I think it's great that the school is giving us this option," junior Chelsea Wehking said Tuesday. "I've heard some kids say they'd be too embarrassed" to go into town – Shippensburg, permanent population about 6,000 – and buy Plan B.

Police in Mexico have seized a record 15 tonnes of pure methamphetamine in the western state of Jalisco.

Mexican cartels already control the supply of marijuana, cocaine and heroine to the US and now they are vying to dominate the methamphetamine market.According to the UN, the record haul is twice the total amount of methamphetamine seized in Mexico in 2009.

The record seizures indicate the growing market for the deadly synthetic drug.

Cancer-Deterring Drug Found to Harm Bones


Cancer-Deterring Drug Found to Harm Bones
The finding, published online Monday in The Lancet Oncology, could make women more reluctant to use the drug, exemestane, and it deals a setback to the notion that one day healthy people might take medicine to reduce their risk of getting cancer.

2010 Tour de France Winner Found Guilty of Doping

After 17 months of legal wrangling and an investigation by Basque authorities to determine the source of some purportedly tainted steaks that Alberto Contador said he ate during the 2010 Tour de France, an appeals court ruled Monday that Contador, a three-time winner of the Tour, was guilty of doping.

Cancer Group Backs Down on Cutting Off Planned Parenthood



This morning, the Susan G. Komen for the Cure foundation reversed its decision to cut off funding for breast cancer screenings arranged by Planned Parenthood.
At a time when political leaders never admit fault and rarely accept responsibility, the Komen foundation did both, and that’s worth celebrating. “We want to apologize to the American public for recent decisions that cast doubt upon our commitment to our mission of saving lives,” the announcement said.
But the announcement was also somewhat disingenuous. The decision provoked outrage from supporters of the world’s largest breast cancer charity because it was unmistakably political. It came during a stepped-up campaign against Planned Parenthood by anti-abortion groups. And yet the foundation claimed it was “deeply distressed” at the suggestion that they’d acted “for political reasons or to specifically penalize Planned Parenthood.”

Public health: The toxic truth about sugar

Authorities consider sugar as 'empty calories' — but there is nothing empty about these calories. A growing body of scientific evidence is showing that fructose can trigger processes that lead to liver toxicity and a host of other chronic diseases1. A little is not a problem, but a lot kills — slowly (see 'Deadly effect'). If international bodies are truly concerned about public health, they must consider limiting fructose — and its main delivery vehicles, the added sugars HFCS and sucrose — which pose dangers to individuals and to society as a whole.




Excessive consumption of fructose can cause many of the same health problems as alcohol.
